i Naftfm'c and Object of thcln'vcnt'ion.

My invention is for a beam or girder made of wood, and banded with ironor other material for the purpose of strengthening it, and thus make allsuch work stronger and lighter.

Description 0f thc Drawing forming part of this Specification.

A is the beam or girder, of wood, thirty feet in length, three inchesthick, and twelve inches wide. It may be longer or shorter, thicker orIt is intended for thinner, wider or narrower.

tiis beam'to sit up edgewise. B, the band which strengthens it; O, thespikes or bolts with which it is secured to the beam. D D are strapswhich pass round a beam or girder. E E are screws for tightening up 'thebands; F F, nuts on the ends of the screws. G are A teeth in the bandsat the ends of the beam or girder, where the ends rest, to prevent themfrom slipping and to hold 'them tirmly in position.

This invention is for bridges and for buildings, and for every kind ofbeam or girder and stringers of wood, wherever used. It will be verystrong, and take the place of truss-work in a great many places, andallow of using wood much lighter than that used in the ordinary way.
